Abstract: Based on the actual situation of the chemical industrial park, this paper establishes a more comprehensive safety evaluation index system, ascertains the index weights by an improved analytic hierarchy process (AHP), puts the fuzzy theory to the safety comprehensive evaluation, and obtains the safety level of a chemical industry park. Then by using the theory and methods of this article, we evaluate the safety level of one chemical industry park named A, obtain the safety level of the park, identify the deficiencies which exist in terms of accident prevention and risk control in this chemical industry park, and put forward the corresponding measures and suggestions.
